Natural disasters, also known as natural disasters, natural disasters, famines, etc., refer to abnormal phenomena that occur in nature, which can cause serious disasters to surrounding organisms and human society.

This is the definition of natural disasters by human beings.

Putting aside the explanation of Wen Xuan, in fact, since the beginning of human beings, they have been fighting against various natural disasters and paying enough costs.

In winter, snow disasters can kill people.

In the summer, there is a drought, and people die.

Plateaus, avalanches, will kill people.

Coastal, tsunami, will kill people.

In normal times, typhoons, floods, earthquakes, volcanic eruptions, and meteorite impacts still kill people.

Natural disasters often erupt suddenly and unpredictably, resulting in heavy losses. Of course, over the long years, human beings have also learned to recognize natural disasters and prevent them in various ways.

For example, on snow-capped mountains, it is absolutely impossible to make loud noises and strong vibrations to prevent avalanches. On large rivers, numerous dams and reservoirs are built to regulate the volume of water in rivers and prevent flooding. In addition, artificial rainfall is used to alleviate drought, meteorological satellites are used to warn and evacuate people to reduce the damage caused by typhoons, and so on.

However, under the terrifying power of nature, the power of human beings is too small, and they can only prevent, avoid, and reduce losses, and it is really too difficult to resist.

Take typhoons, for example.

Typhoons are the most common natural disasters, which are frequent, powerful, and have a wide range of impacts, causing serious losses.

Some people have asked whether it is possible to eliminate typhoons with the level of science and technology on the modern earth. For example, detonate a high-yield nuclear bomb in the center of the typhoon, destroy the typhoon, and eventually let the typhoon subside.

In fact, no.

The heat released by an ordinary mature typhoon is basically equivalent to detonating a nuclear bomb with a yield of 10 million per 20 minutes, and the heat released per hour is thousands of times that of the Hiroshima atomic bomb. If it were just a few ordinary nuclear bombs, detonated in the center of a typhoon, it would not have much effect at all.

Bottom line: Nature is the master of the planet, and humans are nothing more than parasites on the surface of the earth.

65 million years ago, an asteroid with a diameter of about 11 kilometers hit the Gulf of Mexico, causing the Cretaceous mass extinction, which wiped out about 75% of the world's living things, including dinosaurs, and the earth had no impact.

The Earth has been around for nearly 4.6 billion years, and it is no surprise that it will continue to exist for billions of years.

Human beings, who only have a few thousand years of civilization and millions of years of biological evolution, are really not worth mentioning to the earth, at least for the time being.

As for the earth's natural disasters, human beings can only try to avoid and prevent them, but they cannot resist them.

And a headache is that some common natural disasters can be detected in advance because of obvious signs, and there is enough time to prevent them.

And some uncommon natural disasters, which cannot find any abnormal state before they happen, will quickly take a large number of lives, making it impossible to prevent it, so they can only turn to the goddess of luck for protection. This kind of natural disaster, one of the most famous ones, is called ...... The lake flips.

There are very few recorded cases of natural disasters such as lake overturning, only two so far, but each of them has caused considerable casualties.

The first case, Lake Monauen.

Lake Monauen, located in Cameroon, a country in west-central Africa, was the scene of a natural disaster on August 15, 1984.

When a natural disaster occurs, it happens without warning, and it happens with great speed, like a god of death wielding a scythe, taking lives one by one with precision, and then hiding in the darkness.

People affected by natural disasters have no ability to resist at all, let alone transmit messages to the outside world for help, and all of them die in a very short time. In the case of natural disasters, it was not until unrelated people, due to accidental circumstances, entered the scene after the outbreak of natural disasters that they realized that the situation was wrong.

The first person to be found was Ahaji Abdu, and while he was on his way, he saw dead bodies strewn across the road, cars crashing off the road, and no one survived

According to later statistics, a total of 37 people died in this natural disaster.

This number is nothing, and the most important thing is that the person who died did not show any signs of struggle, as if he suddenly died of some kind of acute infectious disease, which caused a huge panic at one time, and it was only after a long time that it was investigated.

The second case, Lake Nyos.

Lake Nyos, also located in Cameroon, a country in west-central Africa, was struck by a natural disaster in the early hours of August 21, 1986, two years after the first case.

When the natural disaster occurred, it was late at night and it was still located in a densely populated area, so a large number of people who were sleeping were collectively killed before they could react.

Eyewitnesses who entered the area afterwards described no one in sight, or that they were all dead.

Because it is located on the outskirts of the area, an eyewitness who was extremely lucky enough to recover a life from the disaster described that he was standing alone in the pile of dead people, the house was full of dead people, cows, sheep, and dogs were all dead, and there were 56 people in the family, 53 of whom were not breathing.

According to posthumous statistics, more than 1,700 people died in this natural disaster, and countless livestock died!

This apparently caused a huge panic, especially just two years after the first case.

For this reason, scientists from all sides rushed to conduct rigorous investigation and research, and concluded that the events of Lake Nyos and Lake Monauen were caused by the flipping of the lakes.

What is Lake Flip?

It turns out that Lake Nyos and Lake Monauen are not ordinary lakes, and there is a magma zone below the bottom of the lake. The presence of this magma belt allows carbon dioxide (CO2) to continue to leak into the water, accumulating at the bottom of the lake with slow flow and high water pressure.

When the carbon dioxide accumulates to the limit, it will erupt, and hundreds of thousands of tons of carbon dioxide will quickly rush out of the lake and spread around.

Because carbon dioxide is 1.5 times denser than air, a lot of carbon dioxide is like a thick carpet on the earth, driving away almost all the air wherever it goes, first creating a high-concentration carbon dioxide area, then creating a pure carbon dioxide area, and then it will dissipate after a long time.

Carbon dioxide is a gas that is part of the air and is not harmful at low concentrations, such as 0.04%.

But when the concentration rises to 1%, it will make people feel stuffy, dizzy, and palpitated.

When it reaches 5%, it will make people feel breathless, headache, and dizziness.

When it reaches 10%, the human body functions will be seriously confused, causing the person to lose consciousness, become unconscious, stop breathing and die.

As for the higher concentrations, reaching the level of pure carbon dioxide, not to mention humans, as long as plants, animals, and microorganisms that rely on oxygen for aerobic respiration cannot survive.

That's the lake flip!

Some people have given this kind of natural disaster a name, called ...... Farts of the Earth.

Well, fart of the earth.

The Earth farted and then took hundreds of lives.

And this is the power of natural disasters in nature.

......

Taklamakan Lake, a lake that periodically undergoes "lake reversal", is certain.

However, when Richard was first interested in Taklamakan Lake, he was unaware of this. The interest in Taklamakan Lake is entirely because of the name.

After all, not every desert is called Taklamakan . The name of the desert on the earth was actually pressed on a lake in the current world, which made Richard curious.

Later, he heard about the legend of the Death Reaper of Lake Taklamakan from the wizard Teddy, and Richard was eager to explore the secrets of the lake.

There was a lot of speculation at the time, and later on, in the process of exploring the small village of Artis, more discoveries were made. After entering the lake and looking at it, it was finally determined that Taklamakan Lake was a lake that would have a "lake flip" natural disaster.

Then everything can be explained.

In the legend of Lake Taklamakan Lake, the so-called Grim Reaper is nothing more than hundreds of thousands of tons of carbon dioxide gas accumulated at the bottom of the lake. It takes a few hundred years for death to wake up from its slumber and take away all the life it sees, because it takes a long time for carbon dioxide to reaccumulate after each eruption to the outside world. Hundreds of years is a cycle of accumulation.

Knowing this, Richard raised his vigilance against Lake Taklamakan and warned Nancy and Gro that it was best to stay away from the lake.

Although he can see that the amount of carbon dioxide accumulating at the bottom of the lake is not far from the limit and will not erupt to the outside world for decades, many things are not absolute.

A small earthquake, or a boulder falling into the water, can upset the delicate balance between the carbon dioxide at the bottom of the lake and the water in the lake, allowing the carbon dioxide to be released prematurely. At that time, the killing effect and killing range may be somewhat reduced, but those in the core area who are not sufficiently prepared will definitely die.

With this figured out, the matter was over, and with the meeting convening, Richard threw Lake Taklamakan aside. After all, his main purpose is the treasure of the Black Spirit King, the ultimate secret of the Black Spirit Empire, not the geographical expedition.

He just wanted to wait until after the exchange conference, and find a way to stay and continue digging and searching for the small village of Artis, and not put too much effort into a single lake, even if this lake was very rare and the whole earth had been proven three so far.

But who knows, things turned out unexpectedly, the exchange conference turned out to be a big trap, and the Deep Blue Castle actually colluded with the mysterious organization to kill all the wizards who participated in the meeting.

Richard was not very interested in this kind of trap, conspiracy and the like, and was not prepared to participate in it at all, and after helping Gro, Nancy and others break through, he was ready to leave.

I was thinking more about one thing: after the Deep Blue Castle made such a fuss, the entire East Coast was in chaos, and the surroundings of the Deep Blue Castle became extremely dangerous. If you want to continue digging and looking for the small village of Artis, I'm afraid it's going to be difficult, and you need to find another way.

It's like when you're thinking about a solution, a new problem arises. The black-robed wizard of the mysterious organization, for some reason, actually regarded him as a target for killing, and mobilized a large amount of strength to surround and kill, so that he couldn't escape even if he wanted to.

In the midst of the crisis, he remembered the dangerous existence of Taklamakan Lake. He simply fled to Lake Taklama, and when the enemy did not notice anything wrong, he released a large amount of carbon dioxide at the bottom of the lake in advance to solve all his troubles.

He didn't feel anything wrong with this kind of borrowing behavior, nor did he feel that he couldn't win.

In any case, with this method, he didn't need to bother killing people at all, or continue to run away, and now he only needed to receive the loot from the many corpses.

Well, receive the loot.
